[Guruprasad (lgp171188)]

Before:
```
Warning: You configured snap `go` but you used a deprecated format.
Please use
...
-name: go
 classic: True
...
instead.
Please refer to the documentation for an overview of supported formats.
```

After:
```
Warning: You configured snap `go` but you used a deprecated format.
Please use
...
- name: go
  classic: True
...
instead.
Please refer to the documentation for an overview of supported formats.
```
